KODAK PLUS-X AEROGRAPHIC Film 2402

AS-45 KODAK PLUS-X AEROGRAPHIC Film 2402 KODAK PLUS-X AEROGRAPHIC Film 2402 is a panchromatic, negative camera film with medium speed, medium-high contrast, and extended red sensitivity for the reduction of atmospheric-haze effects. The ESTAR Base provides flexibility, moisture resistance, high tear resistance, and excellent dimensional stability. This film has a thin, highly-hardened emulsion for high-temperature rapid processing in modern continuous-processing machines. This film can be processed in the KODAK VERSAMAT Film Processor, Model 11 or 1140, with KODAK VERSAMAT 885 Chemicals, KODAK VERSAMAT 641 Chemicals, or KODAK VERSAMAT Chemicals, Type A. It can also be processed at normal temperatures in conventional rewind equipment, such as the Gordon/Morse M-10 Developing Outfit (Military Designator: B-5) using a variety of Kodak black-and-white developers. APPLICATIONS KODAK PLUS-X AEROGRAPHIC Film 2402 is for general use in reconnaissance aerial photography at medium to high altitudes. Because of the dimensional stability of the ESTAR Base this film can also be used for mapping purposes. It can also be used in multispectral aerial photography. This film is capable of providing sharp negatives that are particularly suitable for first-order printing. BASE 3.9-mil (0.10 mm) ESTAR Base with dyed-gel backing TOTAL FILM THICKNESS The nominal total thickness (unprocessed) of this film is 4.40 mils (0.112 mm). This includes emulsion 0.30 mil (0.007 mm), base 3.9 mils (0.10 mm), and dyed-gel backing 0.20 mil (0.005 mm). WEIGHT The weight of 2402 Film (unprocessed), conditioned in equilibrium with 50 percent relative humidity, is 0.035 lbs ft 2 (0.0159 kg ft 2 ). SAFELIGHT Total darkness is required. EXPOSURE Aerial film speeds (ISO A or EAFS) should not be confused with conventional film speeds which are designed for roll and sheet films used in pictorial photography. The characteristics of aerial scenes differ markedly from those of ordinary pictorial or ground scenes because of the smaller range in subject luminances, atmospheric haze conditions, and other factors. Therefore, different film-speed parameters are used to relate aerial-scene characteristics to practical exposure recommendations. The KODAK Aerial Exposure Computer, KODAK Publication AS-10, has been published based on the aerial film speed criterion. Nominal speed, daylight (no filter): EAFS or ISO A 200 Other suggested aerial film speeds for processing these films in the KODAK VERSAMAT Film Processor, Models 11 or 1140, using VERSAMAT 885 Chemicals, 641 Chemicals, and Type A Chemicals can be found in the sensitometric data tables. Note: The aerial film speeds given in this publication were obtained by rounding the calculated values to the nearest cube root of 2 step (equivalent to 1/3 stop).

Typical Camera Exposure A typical exposure for this film is approximately 1 500 second at f 11. This exposure is based on a solar altitude of 40 degrees, a clear day, an aircraft altitude of 5,000 feet, and a speed of ISO A 160 (no filter). When using an aerial camera equipped with an antivignetting filter, or other filter, it is important to increase this typical exposure by the filter factor of the filter used. Reciprocity Characteristics No exposure or development time adjustments are required for exposure times from 1,000 second to 1 100 second. At 1 10,000 second, adjust the lens aperture by +1 2 stop and increase the development time by 10 percent. At 1 10 second, adjust the lens aperture by +1 2 stop.

STORAGE For consistent results, all aerial films should be stored under fairly constant conditions. Kodak aerial films are usually packaged in equilibrium with 40 to 50 percent relative humidity. High temperatures or high humidity may produce undesirable changes in the film. Unexposed Film Store unexposed film in a refrigerator at 55 F (13 C) or lower, or freezer at 0 to -10 F (-18 to -23 C), in the original sealed container. If the film is stored in a refrigerator, remove it about 2 hours before opening; if stored in a freezer, remove it about 8 hours before opening. A sufficient warm-up time is necessary to prevent moisture condensation on cold film otherwise, moisture spotting, ferrotyping, or sticking may occur. Exposed Film Keep exposed film cool and dry. Process the film as soon as possible after exposure to avoid undesirable changes in the latent image. If it is necessary to hold exposed but unprocessed film for several days (such as over a weekend), it should be resealed and refrigerated at 40 F (4 C) or lower. Before unsealing and processing exposed film that has been held in cold storage, follow the warm-up procedures described for unexposed film described above. Processed Film For best keeping, store processed film in a dark, dust-free area at 50 to 70 F (10 to 21 C) and 30 to 50 percent relative humidity. Preferably, store negatives on the spool or in individual KODAK Sleeves. High relative humidity promotes the growth of mold and causes ferrotyping. Very low relative humidity causes excessive curl and brittleness. Avoid storage temperatures over 80 F (27 C). PROCESSING KODAK VERSAMAT Processor, Models 11 and 1140 KODAK PLUS-X AEROGRAPHIC Film 2402 can be processed in the KODAK VERSAMAT Film Processor, Model 11 or 1140 with KODAK VERSAMAT 885 Chemicals, KODAK VERSAMAT 641 Chemicals, or KODAK VERSAMAT Chemicals, Type A. Mechanized processing in roller-transport processors offers the advantages of uniform treatment of all portions of the roll, freedom from banding, and absence of significant density variations from ends of the roll to the center. Refer to the operator s manual for the processor set-up information, but in all cases, the fixer replenisher should be introduced into tank No. 5 of the processor with a countercurrent flow to tank No. 3, where it overflows to a collection or recovery system. General instructions for setting the machine dryer temperature are included in these pages. However, the temperature of the dryer may require some further adjustment, depending upon the ambient temperature conditions in the processing area. Usually it is best to set the temperature approximately 3 F (2 C) above that required to dry unexposed, processed film.

REWIND OR SPIRAL REEL PROCESSING KODAK PLUS-X AEROGRAPHIC Film 2402 yields optimum results with modern, high-temperature, continuous-processing machines. It can be processed in rewind equipment or on spiral reels, although these methods are not primary processing recommendations. Customers wishing to use spiral reels or rewind equipment such as the Gordon/Morse M-10 Developing Outfit (Military Designator: B-5) may contact Aerial Systems for information on exposure, processing chemicals, process cycles, and general recommendations. DIMENSIONAL STABILITY The dimensional stability of aerial films is of particular interest and importance in accurate mapping and in the reproduction of maps. Dimensional stability is an all-inclusive term. In photography, it applies to size changes caused by changes in humidity and in temperature, and by processing and aging. The absence of solvent in ESTAR Base is one of the reasons why ESTAR Base films show excellent dimensional stability. The dimensional properties of ESTAR Base may vary slightly in different directions within a sheet; the differences that may exist, however, are not always between the length and width directions. Temporary Dimensional Changes Thermal Coefficient of Linear Expansion: 0.001% per degree F of change 0.0018% per degree C of change Humidity Coefficient of Linear Expansion (Unprocessed): 0.0018% per 1% change in relative humidity Permanent Dimensional Changes Processing Dimensional Change: -0.03% to +0.03% shrinkage to swell Aging Shrinkage of Processed Film: 0.03% 1 week at 120 F (49 C), 20% RH 0.03% 1 year at 78 F (25.5 C), 60% RH 4 KODAK PLUS-X AEROGRAPHIC Film 2402 AS-45
